Abstract

A system and method for filtering Program Service Name (“PSN”) data includes a processor, an antenna in communication with the processor, a display device in communication with the processor, and a memory unit in communication with the processor. The memory unit contains instruction executable by the processor to configure the processor to receive a signal from a wireless source via the antenna, the signal having PSN data, determine if the PSN data is a static PSN or a slowly updated PSN, and display the PSN data on the display device if the PSN data is a static PSN or a slowly updated PSN.

Claims

1. A method for filtering program service name (“

PSN”

) data, the method comprising the steps of;

receiving a signal from a wireless source, the signal having PSN data;

determining if the PSN data is a static PSN or a slowly updated PSN; and

displaying the PSN data on a display device if the PSN data is a static PSN or a slowly updated PSN.

2. The method of claim 1, further comprising the step of:

receiving a first PSN from the wireless source

determining the amount of time needed to receive the first PSN from the wireless source; and

displaying the PSN data on the display device if the amount of time need to receive the first PSN from the wireless source is greater than a threshold time.

3. The method of claim 2, wherein the threshold time is about 2.5 seconds.

4. The method of claim 2, further comprising the steps of:

receiving a new PSN message;

determining if the new PSN message is the same as the first PSN; and

displaying the PSN data on the display device if the new PSN message is the same as the first PSN message for a period exceeding a validation time.

5. The method of claim 4, wherein the validation time is about 6 seconds.

6. The method of claim 1, further comprising the steps of:

receiving a new PSN;

determining if the new PSN is the same as a previously collected PSN;

calculating the time difference between receiving the new PSN and the previously collected PSN if the new PSN is not the same as the previously collected PSN; and

displaying the PSN data on the display device if the time difference between receiving the new PSN and the previously collected PSN is less than a PSN change time threshold.

7. The method of claim 6, wherein the PSN time change threshold is about 6 seconds.

8. The method of claim 6, wherein the calculating step is repeated to prevent a false positive error from occurring.

9. The method of claim 8, wherein the calculating step is repeated three times.

10. The method of claim 1, further comprising the step of displaying blank characters on the display device if the PSN data is not a static PSN or a slowly updated PSN.

11. The method of claim 10, wherein the blank characters are a plurality of spaces.

12. The method of claim 10, further comprising the step of storing the PSN data for later use.

13. A system for filtering Program Service Name (“

PSN”

) data, the system comprising;

a processor;

an antenna in communication with the processor;

a display device in communication with the processor; and

a memory unit in communication with the processor, wherein the memory unit contains instructions executable by the processor to configure the processor to receive a signal having PSN data from a wireless source via the antenna, determine if the PSN data is a static PSN or a slowly updated PSN, and display the PSN data on the display device if the PSN data is a static PSN or a slowly updated PSN.

14. The system of claim 13, wherein the system is a distributed system.

15. The system of claim 13, wherein the system is installed in an automobile.

16. The system of claim 13, wherein the instructions further configure the processor to receive a first PSN from the wireless source, determine the amount of time needed to receive the first PSN from the wireless source, and display the PSN data on the display device if the amount of time need to receive the first PSN from the wireless source is greater than a threshold time.

17. The system of claim 16, wherein the threshold time is about 2.5 seconds.

18. The system of claim 16, wherein the instruction further configure the processor to receive a new PSN message, determine if the new PSN message is the same as the first PSN, and display the PSN data on the display device if the new PSN message is the same as the first PSN message for a period exceeding a validation time.

19. The system of claim 18, wherein the validation time is about 6 seconds.

20. The system of claim 13, wherein the instructions further configure the processor to receive a new PSN, determine if the new PSN is the same as a previously collected PSN, calculate the time difference between receiving the new PSN and the previously collected PSN if the new PSN is not the same as the previously collected PSN, and display the PSN data on the display device if the time difference between receiving the new PSN and the previously collected PSN is less than a PSN change time threshold.

21. The system of claim 20, wherein the PSN time change threshold is about 6 seconds.

22. The system of claim 20, wherein the instructions further configure the processor to repeat calculating the time difference between receiving the new PSN and the previously collected PSN if the new PSN is not the same as the previously collected PSN to prevent a false positive error from occurring.

23. The system of claim 13, wherein the instructions configure the processor to display blank characters on the display device if the PSN data is not a static PSN or a slowly updated PSN.

24. The system of claim 23, wherein the blank characters are a plurality of spaces.
